Interested in hearing more about this.
Pass it off as tutoring, make a flyer and stick it up in the international student section. If you've got pretty handy computer skills it's not hard to make one that they'll notice. There'll no doubt be a few up there, but undercut them for a while until you get to a point where people start to realise that you'll do a good job at what you're offering, which is when word of mouth kicks in.
As a tutor you can charge whatever you want. One guy I knew was charging $40 an hour to look over their work with a fine tooth comb, but rather than just a basic proofread, he'd take their ideas and rewrite it for them. There's a massive demand for this sort of thing, so get in while you can. It definitely was a constructive use of time between classes that I would have otherwise wasted.
